Incredible sampler and synth combo...

This one is probably gonna be one of the most useful tools in a musicians toolbox, with mindboggling possibilities and beautifully complex sounds with an almost effortless worksurface. This developer delivers on this and all his other apps especially the synth ones like this and the drc.

Fantastic Synth

I love this synth because it has such a unique sound, and it works really well as an AUV3, including in BAM, which you should also check out.

MehrspurAufnahmen in Cubasis 3.8.3

Ich versuche mit diesem ios Synth als Audiounit Mehrspuraufnahmen zu machen, aber dies funktioniert nicht. Es werden zwei Audio Units von FRMS geladen, doch wenn ich das Programm schließe und wieder öffne, wird die weitere Spur nicht mehr mit dem FRMS geladen. Gibt es eine Klärung für das Problem - mit anderen iOS Synths klappt dies? Wakanoa

This is a lovely, stable, powerful, flexible synthesiser.
Great design. Works well on phone and iPad.
The IAPs are very high quality and interesting.
My go-to granular. 5 stars for sure. Thanks. 👍🏼🎶

We’re thrilled to hear that FRMS is your go-to granular! That means a lot to us. We’re also glad you’re enjoying not only FRMS but its expansion packs as well. That’s awesome 😁

Wow, Klangwelten kreieren vom Feinsten

Please open the 4MB lock in FRMS so that also larger Wave files are loaded in FRMS and Parts of it can be cut and stored. FRMS has the cutting function on board from the absence. And how about an X and Y touchpad as a new feature? Would do great in FRMS. Keep it up. I think your approach to developing music apps is great.

One of the Best

I guess you could say that this synth is perfect because I can’t really think of any way it could be improved. From the sounds, the possibilities, the interface…it’s all there to instantly get creative. Freakin’ fantastic it is.

Textural Ambient Bliss

This is the granular synth you’re looking for! I have almost every one on the App Store and this is the one I pull up the most. Incredible sound design potential with 4 simultaneous engines that can be oscillators or sample-based grains, or a blend of both. Worth mentioning too that I bought 4-5 of the preset packs and they did NOT disappoint! Creative and inspiring right out of the box. All hail FRMS!

Thank you very much for your feedback and for letting us know that FRMS is a great sound design companion. Our goal is for the expansion packs to be just as creative and fun to use as FRMS itself and to show FRMS potential. We're glad you're enjoying them ☺️

Hands down the best!

This synth is incredible. Low on cpu. Terrific sounds.

No refund????

Thought I had 15 days to ask for refund in EU but apparently not with Apple. I wanted a live sampler but this on is not working as expected… Please refund I already uninstalled the app…

The Best

Granular processing has been a passion for many years. This is by far one of the best apps available.

MIDI input not working?

I’m running FRMS in AUM, but none of the MIDI sequencers I use are having any effect on triggering FRMS. Bit strange, as it’s usually fine with all of them.

Previous, and current versions.

Hi! Thank you for your feedback. We just tested it, and everything worked fine on our end. Are you able to play FRMS using the internal keyboard? Can you please reach out to us through our website so we can help you figure out what might be causing this issue? Best regards

Supreme presets

As in their other apps, Imaginando have curated an impressive set of presets which really showcase the qualities of FRMS.

Finally a desktop-grade Granular on iOS

iOS has about 3 or 4 apps available on its platform that utilize Granular, but FRMS stands up there with FM features, four layers, and a modulation matrix. Since its launch in 2020 Imaginando has continued to breathe life into their Granular flagship, including advanced UI resolution for HD screens, a performance boost, and VST3 support. It’s also available on Android, something few iOS developers have the time to invest into. Overall it’s one worth adding to your repertoire whether you’re on desktop or iOS. Here’s to a productive 2025 for Imaginando. 🎊

Check out the Foley voices (in-app purchase)

It’s hard to find something that stands out in the iOS environment. There’s just too much good stuff. However, I have a fondness for this company, they are really engaged and creative!

For me, the presets made out of Foley samples make this app. Not only is it encouragement to make your own, it’s also an acknowledgment that not everyone wants to learn everything about every app. Sometimes it’s all about finding something easy to use that speaks to you. Thanks.

Export/mixdown/freezing bug

The granular layer is not rendered correctly either when the track is frozen in the DAW or during the final mixdown. Because of this, the synthesizer is useless in production.
I wrote about this to support several times, the developer confirmed the presence of the problem, but it's been over a year and they haven't fixed this bug.
I would love to make a refund of the purchase, but too much time has passed and Apple won't let me do it.

Hi. We have worked on this issue and we ensured it was working correctly on Logic Pro (you can see this in our changelog). Can you please tell us which host are you using so we can replicate the problem and fix it? Thank you! Best regards

Doesn’t work over Bluetooth. Expansions cost too much.

I try to play this over my Bluetooth amp for a simple drone and it never works. You can’t disable the microphone either. Its automatically on but not really on it just gives a bunch of feedback without picking up a signal.

Still to many bugs with this software.
Audio won’t play over headphone jack either.
Please fix the mic issue. There is no mic off button so the app screams and feeds back into itself immediately upon launch.

You seem to be experiencing some unusual behavior with the input. You should only hear the input while there are active grains. Please contact us through our contact page so we can assist you with this issue. Thank you for your feedback.
